Abstract

The invention relates to a novel process for preparing chlorodiphenyl ethers of the formula I <IMAGE> (I) in which R is hydrogen or chlorine, which comprises heating a material of the formula III <IMAGE> (III) in which X is one equivalent of an alkali metal or alkaline earth metal ion and R is as defined above, in an excess of a dichlorobenzene of the formula II <IMAGE> (II) in the presence of a copper catalyst and of an aprotic solvent as cocatalyst at temperatures of 120 DEG -220 DEG C.
